In detail

  • Slide 7 quotes 104%: finance's unreconciled preliminary net revenue retention of 104%.

    Slide 1Polished
  2. Slide 2 of GPT-6 Luna's deck
    Slide 2Polished Data labels collide with the line and markers ('6.4%' and '6.6%' sit on the Starter line)
  3. Slide 3 of GPT-6 Luna's deck
    Slide 3Acceptable The two large callouts repeat the chart values rather than highlighting the contrast in a single concise takeaway.The callout colours (purple and green) do not map to the bars, which are both purple; the green card implies colour coding that the chart does not use

    Slide 4Polished
  5. Slide 5 of GPT-6 Luna's deck
    Slide 5Polished
  6. Slide 6 of GPT-6 Luna's deck
    Slide 6Acceptable Both comparison cards are text-heavy; the supporting evidence takes several lines to scan.The square-cornered accent bars sit on rounded-corner cards, so the corners mismatch and leave visible gaps
  7. Slide 7 of GPT-6 Luna's deck
    Slide 7Acceptable The lower caveat is a dense, small-text paragraph spanning nearly the full slide width; it is harder to absorb in presentation viewing than the rest of the slide.The horizontal divider has a visible break or step at the midpoint
